The Future of Cars

For a glimpse into what automobiles will be like 20 years from now, contributing editor Stuart F.

Some, like Tesla’s current sports cars, will draw their energy from a battery pack. Others, in common with today’s Toyota’s Prius and the 2010 Chevy Volt, will be hybrid designs, relying on both electric motors and small internal-combustion engines. Many forthcoming hybrids will charge batteries by plugging into the electric grid, and hydrogen fuel cells might be a reality. But that is not all that the participants see. Read on.
